I've been working for several weeks on a page for
Philodendron callosum. There is little in any text or journal I
can locate on this odd species. I'd appreciate any help any of you could
offer. If anyone has a copy of the scientific description, I'd love to be
able to read it. And if you have any practical growing information, that
would also be appreciated.

Here's the page as it now stands, but I am still looking for
more information. As always, I appreciate the help of Julius, Leland,
Russ Hammer, LariAnn and Joep on this one.

This is what I have so far. If you think of anything
else, please let me know.
